The Insurance Institute for Highway Safety is releasing a study today that reports that the cameras have reduced fatal crashes by 24 percent in 14 large cities where the devices were introduced between 1996 and 2004.

Crediting them with saving hundreds of lives, Institute President Adrian Lund says the study shows that the red light cameras work.

But National Motorists Association Executive Director Gary Biller disputes the institute's finding that the cameras have reduced deaths.

It is citing previous studies that reportedly found that the cameras increase crashes.

He says there are cheaper alternatives to cameras, such as lengthening yellow lights or improving sight lines.
